Flying vehicles are machines designed to travel through the air. They include various types such as airplanes, helicopters, and drones. Airplanes are commonly used for long-distance travel, while helicopters can take off and land vertically, making them useful in urban areas and for rescue missions. Drones, on the other hand, are often used for aerial photography, surveillance, and delivery services. These vehicles operate based on principles of aerodynamics, which involve the movement of air around them. They are powered by engines that generate thrust, allowing them to lift off the ground. Innovations in technology continue to improve the efficiency and safety of flying vehicles, paving the way for future advancements like flying cars and urban air mobility.
